Twitter got hacked

I read the news on techcrunch http://www.techcrunch.com/2009/07/14/in-our-inbox-hundreds-of-confidential-twitter-documents/ about twitter getting. I just kept wondering why with all the tech guys at twitter you end up being hacked. I really want to know if the hacker is an employee or a former employee of twitter and I would think that is a little forgiveable. But even then, there have to me security checks when you are handling confidential information about peoples account and confidential info. This is totally unacceptable and bullshit. Someone has to step up on their security checks..This situation will even be owrse if the hacker has actually never been an employee of twitter. That will be unforgiveable in tech terms...

What thoughts do you have on this hack...We may wake up one morning and here too that hey facebook got hacked, or yahoo or even gmail? And may be we will stop using the internet and we go back to Stone age or we devise better control mechanisms right now...
